Specification of Letters Patent Patented May 19, 1914.

0 all whom it may concern:

new and useful Battery-Box Support and Insulator-,pf which the followingis a spec fication.

The present invention relates to improvements in battery box supportsand insu lators, more particularly for use in connection with railroadstorage batteries for lighting systems, one object of the inventionbeing the provision of a support and insulator, so constructed andattached, as to prevent any short circuiting' due to the slopping orfoaming over of the acid within the battery and thus removing a greatobjection to thefpresent forms of supports and insulators for batteryboxes.

A further object is to provide a reservoir. to receive thenormaloverflow of acid, so that the same is retained during the evapoEation and is not permitted to drip upon the 001:. \With the foregoingand other objects in view which' wilL-appearl as the descriptionproceeds, the invention resides in the combi+ nation and arrangement ofparts and in the details of construction hereinafter described andclaimed, it being understood that changes inthe precise embodiment ofthe invention herein disclosed can be made within the scope of Whatisclaimed without departing from the spirit of the invention.

In the drawings -Figure 1 is a sectional view through one corner of abattery box with," the present insulator and support in elevation of theinsulator and support per section connected thereto. Fig. 2 is a sidese. Fig. 3 is a top plan view thereof.

Referring to the drawings, the numeral 1 designates the battery box, and2 the insulator and support. This insulator and support is providedwiththe enlargedbore 3' at the lower end centrally thereof, the reducedscrew receiving bore 4, and the, gasket receiving bore 5. A gasket 6preferably of rubber or other insulating material is positioned withinthe .socket 5 about the screw 8, so that a connection is made at suchpoint to prevent any acid from affecting the screw. The cavity formed inthe bore 3 below the headof the screw is filled with-an insulatingmaterial of a plastic cementitious character,

I andthusprotects the'head 'of the screw from corrosion.

The upper surface of the insulator 2.is provided .with the centralcylindridlliboss 10, which. with the curved surface 11 of the apron 13of the insulator-provides theevaporating receptacle 12 upon the uppersurfa at th ins la d arn d, o h t any-overflow of the acid due to theshaking and jarring of the battery box, as is often the case withbattery boxes used in railroad cars, will retain the small overflowamount of the acid to hold the same during the evaporation thereof, theusual small overfilow thus being held from dripping upon the oor.

The rim of the apron 13, as clearly illustrated in Fig.1, is soconstructed that any acid. that may overflow the curved surface 11 andthe lip 13 willbe prevented from work ing upwardly and under theinsulator or support, and consequently will drip therefrom upon thefloor after running over at such point.

From the foregoing description, taken in connection with the drawings itis evident that an insulatorand support of the present character isreadily applied to any form of battery boxpit being especially designedto be used in connection with railway battery boxes, and that afterproperly positioned, the screw 8 is properly protected from thecorrosive efiect'of-the acid due to the-connection of the gasket 5thereto, while the receptacle 12 of the insulator or support provides ameans for receiving and retainlng a certain portion of the acid that mayoverflow therein, such receptacle retaining the same during evaporation.In many cases,

the overflow is so small that the reservoir 12 will take care of thesame and thus the battery support and insulator will not be.

detrimentally afi'ected due. to the acid.

What is claimed is: Y 1. A battery box support and insulator, composedof a body provided with a liquid retaining recess upon the upper surfacethereof and an outwardly and downwardly inclined drip apron. H

2. A battery box support and insulator, composed of a disk shaped bodyprovided with a concentric liquid retaining recess upon the uppersurface thereof and an out-' wardly and downwardly inclined drip apron,said disk being further. providedwith a central bore therethrough'havingaplumenses bore theretnrough, the upper surface of the member beingprovided with a concentric grooveto form an evaporating reservoir, theinner wall of said groove being a straight wall while the outer wall iscurved to converge into the curvature of the upper surface of the disk.

In testimony that we claim the foregoing as our own, we have heretoafixed our signatures in the presence of two witnesses.
